Well OK, I'll admit, I'm a software guy. Anyway, one of the few tools available that actually helps me with management is for brainstorming and its a mind mapping program.
I prefer the free version called "[url=http://freemind.sourceforge.net/wiki/index.php/Main_Page]Freemind[/url]" over the bloated commercial [url=http://www.mindjet.com/us/products/mindmanager_pro6/index.php?s=1]mindma... software but I thought I'd add this for anyone interested in having a free tool for just recording in brainstorming sessions.
I have used it for this on a projector and it works well to throw everyidea up and then just interactively try to group things once the ideas stop flowing in. As mike said in the podcast, seeing everything and having the group try to organize things can really help for a software project. Its not as physical for the whole team, but works well and is recorded when you leave the session.
Hope it helps.
